How to Make It

Step 1

Heat oil in a large sauté pan over medium-high heat. Add the onions and caramelize for 20-30 minutes over medium heat, stirring frequently. If the pan becomes too dry or brown, add 1 tablespoon of water to deglaze the pan. Once they are golden brown, add the wine and cook until reduced. Chill in the refrigerator for 10 minutes.
